There was a map named "Train Station," which was created in 2010 but was released before the New Year celebrations in 2012. After the release, a bug had been noticed; the prop of the tower could be shot through with Shaft. Two days later, the use of this bug became punishable and a week after that, the bug had been completely fixed.

In 2011, Developers decided to make a contest in which it was necessary to turn the turret constantly. A special map called Carousel was developed for this contest. It was assumed that players would not be able to use the supplies on that map (neither purchased, nor bonus boxes). The map was never released. It is worth noting that the main designer of this map was the legendary mapmaker Figishe, who created a lot of maps. Now the map is considered to be lost.

The project of Ricochet turret first appeared in 2009. The turret was planned to be called "Vulcan". Its shots originally did not bounce off surfaces and were blue. At that time, Vulcan / Ricochet was a machine gun, but then the idea of bouncing balls appeared, and that idea later grew into a full-fledged turret, now known as Ricochet.

When Hornet was just in the testing stage, it consisted of five parts: the central part and four side parts, each of which was below the level of the central unit, and on each side blocks there were tracks. Then Hornet changed to its present state because its design was deemed "too futuristic" and the complexities associated with gravity and traction.

Appearance of Shaft in June 2011 caused quite a furore among tankers. After the release, Shaft was bought at a rate of three pieces per second! Straight after that it was changed and paints with protection from Shaft were released. On the next day it was removed from players' Garages, the crystals were given back and the description was changed. Shaft was weak, so it was slightly improved and, before the release, there was an open testing in Test Server. On the first day of testing, the maximum damage of Shaft in aiming mode was 150 - 175 - 200 - 250 HP (for M0 - M1 - M2 - M3), on the second day was 200 - 225 - 275 - 300.

First Gold Box was worth 1 000 crystals. Initially, no one knew how, where and when this bonus would appear. First Gold Box fell on the map "Kungur" when the battle fund was 700 crystals, it was caught by player Noosya. Later, Gold Boxes began to fall almost on every map, but their value was cut to 100 crystals. Now, the drop zones of the Gold Box drop exist on all maps and the value has again been increased to 1000 crystals.

In February 2011, a special modification of Smoky was introduced. It was named Smoky XT. This modification costed about 4000 crystals. It was available for purchase only for one week. Smoky XT was better than Smoky M3 in all aspects.

In 2009, developers decided to create a turret that could deal damage to opponents and heal allies. So Isida appeared. The first concept of Isida could only heal and looked like it had three teeth, something that resembles a model from the Game «Half-Life». Isida was also able to heal itself (by firing into the void). This ability was too strong and was removed. Isida was last modified in February 2017, when the self-healing ability was removed.

During beta testing (May 2009) Tanki Online was awarded at Game Developers Conference in the category "Best Game without a publisher". This says that, while only in the test phase, Tanki Online had gained recognition and fame in the gaming industry.

In the Summer of 2012, there was a special event hosted to holding the European Football Championship. During this action Gold Boxes value was increased several times.

On September 27, 2012, an extraordinary battle called «Kasim vs Sun» took place — the Community Manager of Russian community, Maksim Khusainov, and Tech Support specialist, Kseniya Ignatyeva, fought against each other on Wasp + Smoky combination. Maksim won with a score of 22:19. Tankers could support Maksim and Kseniya by acquiring a special paint in the Garage that costed 100 crystals. 47 341 paints for Kasim were bought, 18 004 for Sun and 4 844 for both players — all those who bought the paint for Maksim received 59 crystals.

Every year on October 31 Tanki celebrates Halloween. In 2012, during the action a special map was created 59 597 times, and a special gold box fell 12,008 times. There were some interesting coincidences: October 30, 2012 the 16666666th tanker registered, and the Tweet made about the special video blog was 666th. In 2014, there were 45 ghosts on a special Halloween map. On October 31st 2015, tankers spent in the game a total of 196 years, and caught 440 000 Gold boxes. The winner of the competition for the best gold catchers was the player Ti-To, who caught 195 boxes and received Viking XT and Thunder XT as an award.

As for the Vulcan, the game designer Semyon Strizhak (known as Hazel-Rah) jokingly promised that "the turret will never be named Vulcan, otherwise I grow two additional fingers on the hand."

If two discounts are applied to an item, they don't add up. Here is how it works: The first discount is applied to the item, and then the second discount is applied to the already discounted price. For example, a 20% personal discount and a 25% sale from a promotion would give you a total of 40% off, not 45%.
